Boats and Streams
Boats and Streams - The other important topic is Boats and Streams is also an extended version of Time, Speed & Distance. The questions related to this chapter hold a good number in all the competitive examinations. The key to crack this chapter is, that one should go through the basic concepts of Time, Speed and Distance and then should relate this with Boats and Streams. The only difference of Boats and Streams with Time, Speed and Distance is of terminologies. Some of the important terminologies and concepts related to boats & streams are as follows:-
Concept Related to Condition
When a boat is going with the stream (Downstream)
When a boat is going against the stream (Upstream)
When the distance covered by boat is downstream is equal to the distance covered by boat in upstream
How to prepare boats and streams?
First of all go through time, speed, distance and trains before coming to boats & streams.
Learn and imagine the things in upstream and downstream.
Learn some tricks related to specific kind of questions repeatedly asked by the examination bodies.
Go through some puzzles related to the concept of the topic for having a great imagination and understanding.
Take a look at questions appeared in the past related to boats and streams.
Take a mock test for having great concept clarity.
Practice questions of Boats and Stream
